The future of *what if* is actually right here and now, as mostly
happening below our two left feet and otherwise in front of our
dumbfounded eyes.

Using our moon as the ultimate shade of our salvation, over sufficient
time and without the human footprint of soot and many other nasty/
toxic contributions, -22.5 w/m2 should by rights bring on one of those
ice ages. However, along with our human soot and thereby of our
continued global dimming (by perhaps yet another percentage point)
that's worth 6.85 w/m2, plus tossing in the added 100 teraWatts of
artificially produced energy should further offset the onset of cold
by another .1956 w/m2, making our new and improved future along with
our (6.85 + 0.1956) = 7.0456 w/m2 as based upon our nifty contribution
of having expanded our oceans, plus much other atmospheric soot and
having introduced those 100 teraWatts into creating a the improved
global thermal budget end result of accomplishing -15.454 w/m2, which
should be just a few watts/m2 short of bringing on that full-blown ice
age.

In other words, with that moon parked at Earth's L1 we'd have
ourselves shade to burn (sort of speak), along with no future shortage
of those winter Olympic locations, as well as we'd have much fewer of
those lethal storms, fewer and less extensive forest fires, and lots
of those badly GW traumatised polar bares and other polar realm
dependent species that should very much thank us.

Of course once again, this perfectly deductive analogy of "what if" is
yet another ideal computer simulation of 3D worthy animation, that
which any supercomputer worth its parallel CPU salt can give us most
all of those matter of fact answers, of whatever these "what ifs" have
to contribute to our future of somehow getting us by as is w/o
relocating our moon, or that of the new and improved results as
artificially created by way of having relocated that moon of ours out
to Earth's L1.

Naturally, those future moon expedition missions for obtaining the
likes of He3 and many other raw elements will end up taking us four
times as long for the to/from commute, but that's a small price to pay
for the salvation of Earth, wouldn't you say!

BTW; a mostly robotic established moon observatory, or simply
utilized as the secondary S-band signal reflector, or whatever radar
image receiving aperture, on behalf of an Earth based or even the
moon--L1--Earth radar imaging alternative, should by rights get
rather impressive, as we'd have the total solar isolation of the
moon's L1 that's facing Earth to accommodate my LSE-CM/ISS w/tether
dipole element reaching to within 2r of Earth (a bit closer if you'd
dare), as well as having the combined (Earth+moon) L2 for
accomplishing a whole lot better solar related science. Again, all of
that being within the existing supercomputer expertise of telling us
exactly those sorts of "what if" matter of hard facts.
